The Effects of a Progressive KNET Approach on Trunk Alignment, Balance, and Gait in Individuals with Stroke

Objective: This study investigated the effects of a progressive trunk stabilization program based on the Kinesiological Neuromuscular Enhancement Therapy (KNET) approach on balance and gait performance in individuals with stroke. Method: Twenty-two stroke patients were randomly assigned to a KNET group (n=11) or a conventional physical therapy group (n=11). The KNET group received a four-week, stage-specific trunk control program emphasizing segmented trunk coordination, sensory-motor integration, and progressive concentric-isometric-eccentric contraction training delivered by a certified practitioner. Balance and gait were assessed using the Berg Balance Scale (BBS), Functional Reach Test (FRT), Timed Up and Go Test (TUG), and 10-Meter Walking Test (10MWT). Nonparametric tests (Wilcoxon signed-rank and Mann-Whitney U) were used for analysis. Results: Both groups showed significant improvements after intervention (p<.05). However, the KNET group exhibited greater gains in BBS and FRT scores, larger reductions in TUG time, and faster gait velocity on the 10MWT, with significant between-group differences in change values (Z, p<.05). Conclusion: The KNET-based trunk control program effectively improved postural stability, balance, and functional gait performance in stroke patients. It may be particularly beneficial for patients presenting with trunk asymmetry or balance deficits during the subacute stage. The KNET approach offers a structured, reproducible rehabilitation strategy that integrates neuromuscular reorganization and movement control, supporting its clinical applicability in neurorehabilitation.
